Title: Improvements in or relating to the printing of continuous films of water-sensitive, organic, non-fibrous materials
IPC: B41F23/04
Filed: 1945-05-14
Abstract: 591,616. Printing. BRITISH CELLOPHANE, Ltd., and BERRY, W. May 14, 1945, No. 12111. [Class 100 (ii)] Printing processes; printing - apparatus combined with drying - apparatus. In the printing of continuous films of water-sensitive, organic, non-fibrous material, by multi-stage rotary printing operations, by continuous passage through a printing-machine, the film is dried so as to reduce the water-content thereof from its equilibrium value, i.e. the value which is in equilibrium with the moisture of the surrounding atmosphere, to a lower value, the dried film is then printed and is subsequently remoistened to raise the watercontent from its lower value to the equilibrium value. The reduction of the water-content is said to reduce the variation of the extension of the films under the action of tensions encountered during passage 'through the printing-machine whereby a high degree of accuracy of register of the impressions is obtained. The film material may be regenerated cellulose, lowly-substituted cellulose ethers such as methyl cellulose and ethyl cellulose, lowly-substituted cellulose esters such as lowly-acetylated cellulose, and lowly-substituted cellulose ether-esters such as lowlyacetylated, lowly-substituted ethyl cellulose albuminous materials such as gelatine, and alginic materials. The water-content may be reduced to a value lying between 5 per cent. and 2.5 per cent., preferably 3.5 per cent., by weight, based on the combined weights of cellulose and softener. In an example for twocolour printing in rotary gravure, a continuous film 1 of regenerated cellulose of the plain type, weighing 32 grams per square metre and containing 15 per cent. of glycerine and 7.5 per cent. of water (based on the combined weights of cellulose and glycerine) is drawn from a roll 2 at a rate of twenty feet per minute, passes through a drying-apparatus 4 provided with an inlet 5 and an outlet 6 for hot air, and over a chill roller 9 to a rotary couple 10, then over a hot drying-roller 11 in a warm dry atmosphere, to remove the volatile ingredients of the ink with little further reduction of the water-content of the film then over a chill roller 12 to a couple 14, to rollers 15, 16 similar to the rollers 11, 12, then through a moistening-chamber 17 provided with an inlet 18 and an outlet 19 for humid air and with sets 20 each comprising a guide roller and an expanded roller, and finally over a chill roller 21 to a take-up roller 22. The chamber 17 is at a temperature of 55‹C. and relative humidity of 7.5 per cent. The parts of the apparatus are arranged so that the lengths of unsupported films are as short as possible.
Patent GB-752684-A (GB)
Title: Process for dyeing and printing fibres of polyacrylonitriles
IPC: D06P3/76
Filed: 1954-04-28
Abstract: Polyacrylonitrile fibres are dyed or printed with a triaryl-methane dyestuff which is free from sulphonic acid groups and which contains at least one and at most two primary amino groups in para-position to the central carbon atom, but no other amino groups.  The aryl residues may contain other substituents, e.g. alkyl, alkoxy or nitro groups or halogen atoms.  The dyestuffs are applied as their salts with, for example, hydrochloric, sulphuric, phosphoric, amino-sulphonic, acetic, propionic, chloracetic, benzoic or salicylic acid.  Alternatively the dyestuffs may be applied in the form of their carbinols and converted into salts on the fibre by the action of acids previously or subsequently applied.  Sparingly soluble dyestuffs may be applied by the dispersion dyeing technique.  Dyeing is preferably effected in a weakly acid bath at a raised temperature and, if desired, under pressure, and the dyeings may be subsequently steamed or subjected to a heat treatment.  Examples are given.

Abstract: 817,325. Respiratory appliances. NORMALAIR Ltd. May 1, 1956 [May 2, 1955], No. 12690/55. Class 81 (2). [Also in Group XXXVIII] In a system in which a warning device p is operated when the respiration rate of the wearer of a mask (not shown) falls below a predetermined value, the mask is provided with a diaphragm a which, on each inhalation, causes switch b to close and a current pulse to be fed to a heater winding d associated with a thermistor e which forms one arm of a Wheatstone bridge which also comprises a similar thermistor f to compensate ambient temperature variations and two resistors g and h of negligible temperature coeffiicent of resistance. The bridge output current is fed to a relay winding k and, under normal breathing conditions, maintains a movable contact m clear of a fixed contact o. When the breathing rate falls below the permitted value, the thermistor cooled during the exhalation period sufficiently to reduce the current through the relay winding k, so that contact m closes on contact o, thus operating the warning device p. The death of the wearer of the mask, or a fault in the apparatus, produces a similar effect. The thermistor e is made of a material of high negative temperature coefficient of resistance, e.g. oxides of copper, uranium, or manganese, and may be in the form of a flat strip, a spirally grooved rod, a thin-walled tube, or a bead encased in insulating cement and located, with the heater coil d, in an evacuated glass tube.
